Condition or disease

Study Type : Observational
Actual Enrollment : 10 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: Assessment of GRASP II Medical Device to Improve Arm Coordination After Stroke
Study Start Date : September 2010
Actual Primary Completion Date : September 2014
Actual Study Completion Date : September 2014

Primary Outcome Measures :
  1. Time to grasp [ Time Frame: 3 sessions ]
    Primary outcome measures are: 1) The time elapsed between the start of grasp (when the finger breaks contact with the thumb) and the start of transport (when the wrist leaves the start position); and 2) The time elapsed between maximum aperture of the hand and peak deceleration of the wrist. Secondary outcome measures are: 1) movement duration, 2) time of maximum aperture expressed as % of movement duration, 3) time of peak deceleration expressed as % of movement duration, 4) amplitude of peak velocity of the wrist, 5) time of peak velocity, 6) time of peak velocity of the wrist expressed as % movement duration, 7) size of maximum aperture, 8) time to close hand from time of maximum aperture, 9) distance to target at time of maximum aperture.

Ages Eligible for Study:   Child, Adult, Senior
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Stroke pateints and healthy volunteers (controls)

Inclusion Criteria:

  1. Damage to the following areas of the brain, all of which may be involved in coordination of reach to grasp confirmed by CT scan: parietal, cerebellar, internal capsule and basal ganglia,
  2. A score of 6 or more on the arm section of the Rivermead Motor Assessment (able to reach and pick up a tennis ball and release on thigh),
  3. Time between start of hand opening and start of hand transport > 60 ms (measured with GRASP).

Exclusion Criteria:

  1. Cognitive dysfunction which prevents understanding of the task,
  2. Severe concurrent medical problems that prevent repetitive reaching (including shoulder pain),
  3. A diagnosis of Parkinson's disease, or
  4. Lack of informed consent.
